Limnological studies on the transboundary Turkish soda lake: Lake Aktas

Abstract

Lake Aktas is a small, shallow, and turbid soda lake located between Turkey and Georgia. During the survey, conductivity, pH, dissolved oxygen, turbidity, NO(3)-N, NH(4)-N, TP, SRP, silicate, major anions (Cl(-), SO(4), HCO(3)(-), CO(3)(-)) and cations (Ca(++), Na(+), Mg(++), K(+)), total chlorophyll, phytoplankton, zooplankton and macrophytes were determined in the lake. The phytoplankton of Lake Aktas consists of Cyanophyta, Chlorophyta, Euglenophyta, Bacillariophyta, Cryptophyta, Dinophyta and Chrysophyta, whereas that of zooplankton consists of Copepoda, Chladocera and Rotifera.
